To obtain test certificates, contact\n [SAS Support](/spectrum-access-system/docs/getting-support).\n- **Certified Professional Installer (CPI) certificate**\n\n SAS provides test CPI certificates, but you can also use the CPI\n certificate provided by your [Training Program Administrator (TPA)](https://cbrs.wirelessinnovation.org/cpi-program-administrator).\n- **Google account**\n\n The Google account credentials that you use to log in to the SAS Portal.\n- **Root of trust**\n\n The list of Google's test instance root certificate authority (CA) certificates\n in the CBSD or DP.\n\nTo test CBSD in the test SAS environment, use any\nof the following connection points.\n\nWhat's next\n-----------\n\n- Learn about [Google's PAL interoperability test suite](/spectrum-access-system/docs/pal-iottest).\n- Learn about [CBSD interoperability with Google SAS](/spectrum-access-system/docs/sas-iottest).\n- Learn about [Spectrum Access System](/spectrum-access-system/docs/quickstart).\n- Learn about [key SAS terms](/spectrum-access-system/docs/key-terms).\n- [Troubleshoot SAS issues](/spectrum-access-system/docs/troubleshooting)."]]
